Policy templates
模板are a source for creating policies from a predefined starting point. Built-in Citrix templates, optimized for specific environments or network conditions, can be used as:
- A source for creating your own policies and templates to share between sites.
- A reference for easier comparison of results between deployments as you are able to quote the results, for example, “…when using Citrix template x or y…”.
- A method for communicating policies with Citrix Support or trusted third parties. You can do it by importing or exporting templates.
Built-in Citrix templates
The following policy templates are available:
- Very High Definition User Experience. This template enforces default settings that maximize the user experience. Use this template in scenarios where multiple policies are processed in order of precedence.
- High Server Scalability. Apply this template to economize on server resources. This template balances user experience and server scalability. It offers a good user experience while increasing the number of users that you can host on a single server. This template does not use a video codec for compression of graphics and prevents server side multimedia rendering.
- High Server Scalability-Legacy OS. This High Server Scalability template applies only to VDAs running Windows Server 2008 R2 or Windows 7 and earlier. This template relies on the Legacy graphics mode which is more efficient for those operating systems.
- Optimized for NetScaler SD-WAN.Apply this template for users working from branch offices with NetScaler SD-WAN for optimizing delivery of Citrix Virtual Desktops. (NetScaler SD-WAN is the new name for CloudBridge).
- Optimized for WAN. This template intends for task workers in branch offices who uses shared WAN or remote locations with low bandwidth connections. The workers access applications with graphically simple user interfaces and little multimedia content. This template trades off video playback experience and some server scalability for optimized bandwidth efficiency.
- Optimized for WAN-Legacy OS. This template applies only to VDAs running Windows Server 2008 R2 or Windows 7 and earlier. This template relies on the Legacy graphics mode which is more efficient for those operating systems.
Security and Control. Use this template in environments with low tolerance to risk, to minimize the features enabled by default in Citrix DaaS. This template includes settings that disable access to the following:
- Printing
- Clipboard
- Peripheral devices
- Drive mapping
- Port redirection
- Flash acceleration on user devices
Applying this template might use more bandwidth and reduce user density per server.
While we recommend using the built-in Citrix templates with their default settings, there are settings that do not have a specific recommended value. For example,Overall session bandwidth limit, included in the Optimized for WAN templates. In this case, the template exposes the setting so the administrator understands this setting is likely to apply to the scenario.
Consider that you are working with a deployment (policy management and VDAs) earlier than XenApp and XenDesktop 7.6 FP3. Also, require High Server Scalability and Optimized for WAN templates. In this case, use the Legacy OS versions of these templates when they apply.
Note:
Citrix creates and updates built-in templates. You cannot modify or delete these templates.
